Author:中認(rèn)聯(lián)科 time:2020-07-08 Ctr:1155

CQC mark certification is one of the voluntary product certification services carried out by the China Quality Certification Center. The CQC mark is applied to indicate that the products meet the relevant quality, safety, performance, electromagnetic compatibility and other certification requirements. The scope of certification involves mechanical equipment and electrical equipment. , Electrical appliances, electronic products, textiles, building materials and more than 500 products. The GB31241 standard for lithium batteries began to be enforced on August 1, 2015, replacing the previous 3306 standard. The certification rule implemented is CQC certification. (It can also be said that the test standard for CQC certification is GB31241) So how do you apply for CQC certification for lithium batteries?
